STEAM-HEATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 448,932,dated March 24,1891.

To ctl whom it may concern.-

Be it known that I, BARTHOLOMEW CAVA- NAGH, a citizen of the UnitedStates, residing atDunkirk, in the county of Chautauqua and State of NewYork, have invented certain new and useful Improvements in Steam-Heat- Iing Apparatus; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which itappertains to make and use thesame.

My invention relates to certain new and useful improvements insteam-heating apparatus, and more especially to that class of apparatusdesigned forheatingprivate dwellings, and has for its object to providea boiler for generating steam that v ill be partially heated by thewaste products of combustion escaping from a stove, the tubes or finespassing through said boiler forming substantially a part of thestove-pipe.

To this end my invention consists in the novel arrangement andcombination of parts hereinafter fully described and afterward pointedout in the claims, due reference being had to the accompanying drawings,forming a part of this specification, wherein- Figure 1 represents aside elevation, partially broken away, of my improved device, a portionof the stove being shown in section; and Fig. 2 a section taken on theline x 00 of Fig. 1.

Referring to said drawings, A indicates the boiler, consisting of awrought-iron cylinder, of any suitable or preferred dimensions, withinthe lower end of which is riveted or otherwise secured a head a, and inthe upper end thereof is likewise secured a head a, said latter headextending or projecting slightly above the cylinder A, in order to fitwithin the elbow of the stove-pipe, as will more fully hereinafter bedescribed. The cylinder A is provided with three (more or less) firetubes or flues B, which extend through the length of said cylinder andare tapped through the heads a a. The head ais preferably secured in thecylinder a slight distance above the bottom thereof to permit thecylinder to be placed over the flange A, commonly placed upon stoves forthe reception of the stove pipe, the fire tubes or fines of thecylindrical Application filed January 28, 1890. Serial No. 338,362. (Nomodel.)

boiler A occupying the place of and serving the purposes of thestove-pipe for conveying away the smoke and waste products of combustionfrom the stove, and at the same time constituting a boiler for-thegeneration of steam for heating purposes. Upon the top of the boiler A,and fitting over the projecting head a, is an elbow C, which isconnected by the usual and ordinary pipe to the chimney or exit-flue.

D indicates a pipe connected to the top of the boiler, and may either betapped through the head a, and thence through the elbow O, or directlythrough the side of the boiler near the top thereof. Said pipe leads tothe radiator or radiators, and is connected to a pipe E at a point abovethe boiler, said pipe E extending thence downwardly to thestove,where itis connected to a coil F, located within the fire-pot orcombustion-chamber F of the stove, the other end of said coil beingconnected with a pipe G, which is tapped through the head a of theboiler.

H indicates a return-pipe leading from the radiator or radiators andconnected with the boilernear the bottom thereof, and conveys the waterof condensation that forms in the radiators and their connections backto the boiler. Said boiler Ais provided with a feedwater cock I forsupplying the boiler with water, and is also provided with a steam-gageK and sight-feed tube water-gage L of the usual and ordinaryconstruction.

' As before described, the boiler A is applied to any form of ordinarystove, either heating or cooking stove or range, and occupies the placeand serves the purpose of the usual stove-pipe, the smoke and wasteproducts of combustion passing up and through the tubes B, and thencethrough the elbow O to the chimney, the escaping heat and waste productsof combustion that would otherwise be wast-ed being utilized to heat thewater contained in the boiler, and convert the same into steam, fromwhence it is led off ,by the pipe D to the radiators for heatingpurposes, the water of condensation being conveyed back to the boilerthrough the pipe H. The

coil 1 being located within the fire-pot or combustion-chamber of thestove and connected with the boiler, as before described,

will always insure a rapid and complete generation of steam, and theboiler will act in conjunction with and as an aid to said coil tomaintain the necessary pressure.

By this invention I am enabled to utilize the escaping heat and wasteproducts of combustion from a stove or range that ordinarily are allowedto escape, and through the medium of the generated steam heat a room orrooms locatedin a distant part of the house.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In combination with a stove, a vertical cylindrical boiler closed atits lower end by an inwardly-projeeting head and fitting over thestove-pipe flange of said stove, and closed at its upper end by anoutwardly-projeetin g head fitting within the stove-pipe, and fire tubesor flues tapped through both of said heads and communicating with thestove and stove-pipe, substantially as shown and described, as and forthe purpose set forth.

2. In comlinnation with a stove, a vertical cylii'idrical boiler A,closed at its lower end by a head a, located above the lower edge of thecylinder forming the boiler, and adapting said cylinder to it over thestove-pipe flange, and closed at its upper end by an outwardlyprojectinghead a, fitting within the stovepipe, fire tubes or fines B, tappedthrough both of said heads and communicating with the stove andstove-pipe, a steam-exit pipe D, return-pipe II, a coil F, locatedwithin the stove, the pipe G, connecting the coil with the bottom of theboiler, anda pipe E, connecting said coil with the pipe D, allconstructed and arranged substantially as shown and described, and forthe purpose set forth In testimony whereof I afli x my signature inpresence of two witnesses.
